# 978515 V-Belt | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta v-belt for engines up to serial number 1025582, weighing 0.091 kg and listed for eight applications across TD and TAD engines. The serial cut-off is what decides it — an engine built after that number takes something else. It supersedes 20701268 and 966916, one of which was catalogued earlier simply as a belt.

## 🔌 Function

Carries drive from the crankshaft pulley to an engine-driven accessory such as the alternator or a circulation pump.

## ⚠️ Common Signs of Failure

-   Squealing from the front of the engine on start-up or under load
-   Charge warning light flickering, or the alternator falling behind
-   Cracks across the back of the belt, or glazed and shiny flanks
-   Black belt dust building up under the pulleys
-   Belt turned over in the groove or thrown off the pulley

## 🛠️ Service Notes

-   Check the engine serial number before ordering — this belt is listed only up to 1025582
-   Belt 978547 shares this exact published weight of 0.091 kg on a wider TWD, TD and TAD fitment, so the two cannot be told apart by mass
